Title: Pre-Heating Filler Metal in Welding or Brazing
IPC: B23K5/22
Filed: 1980-07-01
Abstract: Filler metal is preheated to a temperature just below its melting point. As shown, filler wires or strips 4 are fed through a tube 1 connected to a filler feed mechanism by a flexible sheath (Figure 2, not shown). The tube 1 has a rearward portion surrounded by a cooling coil 2 and a forward portion 7 which is heated by the heat from an oxyacetylene welding or brazing torch 8. The amount of the heating of the portion 7 by the torch is controlled by a slidable heat shield 5. A thermocouple 6, which is part of a disclosed overall control means, detects the filler temperature and controls filler advance, coolant flow through the cooling coil, and heat shield movement. Reducing gas, applied to the workpiece, is interrupted during workpiece changeover. The invention makes it possible to reduce the precious metal content of the filler metal and to reduce consumption of combustible gases. <IMAGE>

Title: Semiconductor chip mountings
IPC: H01L23/485
Filed: 1980-11-05
Abstract: A semiconductor chip with its electrodes 22 connected to corresponding electrodes 25 on a circuit board 24 by solder columns 23 is supported by solder spacers 33 formed on isolated metallised pads 34 on the circuit board, the spacers not wetting the chip. The arrangement is produced by forming solder bumps on the electrodes of the chip and circuit board and applying to the isolated pads layers of a solder of higher melting point and of a thickness less than the combined heights of the solder bumps. The chip is positioned on the circuit board with the solder bumps in contact and the temperature raised. The solder bumps melt and merge to form the columns 23 and the spacers then melt, surface tension causing the chip to be lifted so that the solder columns 23 are drawn into a cylindrical or hour-glass shape. Since the spacers do not wet the surface of the chip no lateral or rotational forces which might displace the chip are generated. <IMAGE>

IPC: B65B1/22
Filed: 1980-12-11
Abstract: A bag filling machine wherein bags to be filled are individually brought along a path 7 to a filling nozzle 2 and are clamped to the nozzle 2. Pressure bars 8, 19, extending transversely of the feed path, are provided one on each side of the bag and are movable towards and away from each other by cylinders 16, 20. To permit use of bags of stiff material which cannot be y pulled over the top of the pressure bar 8, the pressure bar 8 is longitudinally movable (to the full line position) out of the feed path 7 of the bag and is returned (to the dotted line position) after the bag has passed to the nozzle (7). In like manner, the back-pressure plate 34 of a compacting device comprising a vibratory plate 41 and plate 34 is also longitudinally movable out of the path of the bag. After the bag is filled the pressure bars 8, 19, which are mounted on a common support frame 27, can be moved laterally together and pivoted downwardly about an horizontal axis (28) to expel air from the bag. <IMAGE>

Title: Electrodeposition using a scanning electrode
IPC: C25D5/18
Filed: 1981-03-04
Abstract: An electrodeposition method and apparatus particularly suitable for electrodeposition of a substrate (1) of a large area and intricate contour uses an electrode (2) having a small electrode area (2a) adapted to be spacedly juxtaposed with a portion of the substrate to define a small electrodeposition gap (G) flushed with a stream of liquid electrolyte. High- frequency and small mechanical vibrations are imparted to the electrode while an electrodeposition current from a source (16), preferably in the form of pulses, is passed between the electrode and the workpiece, which are relatively displaced by drive means (12-14) to cause the electrode area to sweep three-dimensionally over a selected surface area of the substrate, thereby forming a layer of the electrodeposition thereon of a desired uniform thickness with an increased rate. The electrode is preferably constituted as an electrode assembly (3) comprising an electromechanical transducer (4), a horn (6) and the electrode (2) attached in sequence. The drive means (12-14) responds to a numerical controller (15) to produce a three-dimensional displacement between the electrode assembly (3) and the substrate (1). An automatic electrode changing unit (17-19) is associated with the numerical controller for successively bringing a plurality of different electrodes having different geometrical shapes into electrodeposition positions to act on successive differently-shaped surface regions of the contoured substrate. <IMAGE>

Title: Immunolocalisation
IPC: G01N33/567
Filed: 1982-04-21
Abstract: A method of detecting an antigenic substance, in animal tissue, in which a primary antibody to the substance is raised, labelled with a selected hapten such as DNP and contacted with the substance, after unwanted binding sites on the substance have been blocked by applying a wide spectrum of antibodies obtained from a different animal. Subsequently the primary antibodies are contacted with a bridging antibody e.g. Monoclonal IgM anti-DNP antibody, raised in a different species to be specific to the primary antibody. A detecting agent consisting of an enzyme with the same hapten label, e.g. peroxidase labelled with DNP, is then contacted with and binds to the bridging antibody. Finally the enzyme is reacted with, e.g. diaminobenzidine, to cause visible coloration, by which the antigenic substance is detected.

Title: Pumped hydro system with three reservoirs
Inventor: KINNO HITOSHI
IPC: F03B13/06
Filed: 1983-03-30
Abstract: A pumped hydro system with three reservoirs has a upstream reservoir 4, an upper reservoir 5 and a downstream reservoir 6. Stored river water in the upstream reservoir 4 is pumped up to the upper reservoir 5 by pump 8 using surplus electric power and turbine 9 generates electric power at peak time using the level difference between upper reservoir 4 and downstream reservoir 6 at which mean pump head is about half of mean turbine head. Then turbine output power is larger than pump input power provided both operation times are the same. Low water level 16 of the upper reservoir 5 is higher than ground level 20 such that intake water can be taken out through gate 21. The turbine 9 may also drive pump 8 continuously in order to obtain continuous intake of water from upper reservoir 5. The latter in the arrangement shown is disposed between dams 2, 3 across the river, but in a modification may be disposed away from reservoirs 4, 6. <IMAGE>

Filed: 1983-05-05
Abstract: Bed springs are slid over table (9) and forwarded on conveyor belts passing around shafts (6,7) to be wound up with a paper web into a roll package. The springs are pressed as they are conveyed by second conveyor belts passing around shafts (12, 13, 14) which form a sloping inlet section (16). The second conveyor belts are vertically adjustable on pillars (10) by handwheel (18). The paper web tension is controlled by an adjustable disc brake on the supply roll (Figures 4 and 5). The conveyor belt speed is controlled by a sensor monitoring the speed of the paper web as it travels towards the rolling up unit. The height of the first and second conveyor belts may be increased as the roll package diameter increases. <IMAGE>
